Be it known thatI, SIDNEY V. BURROWS, a citizen of the United States,residing at Chicago, in the countyof Cook and State of Illinois, haveinvented certain new and useful improvements in VVorm-Fresses, of whichthe following is a specification.

T his invention relates to new and useful improvements in presses, andhas for its principal object to provide a device which is particularlyadapted for use at tanneries, paper mills, and similar places whereinthere is considerable waste of wet bark or similar material from whichthe moisture must be expelled before the same can be used profitably forfuel.

nether object of the invention is to provide a device which will removethe greater 'portion of juice from apples or other fruit and reclaimingsaid juice or liquor from which cider and vinegar are made.

i further object of the invention is to provide a press which iscontinuous in operation and which is particularly simple inconst-ruction and effective in use.

`With these and other objects in view, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in which,

Figure 1 is a longitudinal sectional view of press constructed inaccordance with this invention, l

Fig. 2 is a detail fragmentary view of the gearing which drives theworm, and

3 is a transverse sectional View through the cylinder and wormillustrating the detailed construction of the same.

1defer-ring now to the drawings by characters of reference, the numeral1 designates as an entirety the main body portion of the press which issupported on a suitable support 2, the upper end of which terminates inthe ring or band 3, which is arranged to surround the body 1 and .assistin holding the same in proper position.

This body 1, abovereferred to, is formed of a plurality of bars 4; whichare arranged at spaced intervals. while the tapering part lf of saidbody is also formed of a plurality of outwardly tapering bars 5, alsoarranged at spaced intervals. These bars are held in proper position bythe rings 6 which co operate with the ring 3 in holding the device inoperative position as will be clearly Specification of Letters Patent.

seen upon referring to F ig. 1 of the drawings. A suitable frame 7' islocated at the enlarged end of the body 1 and carries the driving gearsand hopper, by means of which the device is fed.

Extending longitudinally through the main body 1 is the continuous worm9, the

end of the worm at the small end of the body portion is held in place bythe bars of the shell and the opposite end by the shaft 10 and bearings11, the shaft 10 extends into a suitable thrust bearing l2 which isbolted on to the frame T. The drive consists of so arranged as toincrease the power, and is termed double back geared drive.

The worm 9 above referred to, is preferably carried on the drum 16. Thisdrum is secured to the shaft 10, hereinbefore referred to, and tapersgradually from the point at which the forward taper of the outer shellbegins to the rear end of the drum which terminates within the hopperhereinbefore referred to. A tapering forward extension 1T is formed onthe drum and also forms a support for the forward portion of the worm asclearly shown in ldig. 1. The worm, above referred to, is carried by theperiphery of the drum 16 and at the reduced end thereof the coils arerelatively widely separated and gradually decrease in their width untilthey reach the largest diameter of the drum from which point theygradually increase in their distance apart until they reach theirmaximum width at the front end of the drum. ln this way it will beclearly seen that the material which is being pressed is much morefirmly compressed through the action of such a constructed worm and drumthan would otherwise be possible.

It will be evident from the foregoing that in use the worin i) is set inmotion through the medium of the belt wheel 13 and gears 14. rThe wetbark or other material is then fed into the machine through the hopper15 and due to the action of the worm 9, will be forced toward thereduced end of the body 1 and out through the opening at the reducedend. This product after having been compressed in this manner will berelieved of the greater portion of liquid which leaves the material andgoes out between the bars 1l and will emerge from the end of the body 1in the form of a compressed mass, which may be cut in desired lengths iuany suitable manner.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be inade in the combination and arrangement of parts as Will fallWithin the spirit and scope of the invention as deiined in the appendedclaims.

Having thus described my invention7 I claiin:

1. A Worin press including a shell having a cylindrical body portion anda tapered front portion, Said body portion being pro vided with anintake opening at its rear end, a druin journaled in and extendinglongi- V tudinally of the body and iront portions,

said druni gradually increasing in diameter from the rear end oi thebody portion to and in the direction oi the front end of the bodyportion and gradually decreasing in diameter troni the 'front end of thebody portion in the direction of the front end of the tapered portion, aWorin on the drum gradually decreasing in pitch from the rear end of thebody portion to and in the direction of the front end of the bodyportion and then gradually increasing in pitch in the direction of thefront end of the tapered portion, and drum rotating means.

2. A Worm press including a shell having a cylindrical body portion anda tapered portion at the front end of the body portion, said bodyportion having an intake opening at its rear end, an imperforate drumjournaled in and extending longitudinally of the shell, Said drumgradually increasing in diameter from the rear end of the body portionto and in the direction of the front end of the body portion and thengradually decreasing in diameter in the direction of the front end ofthe tapered portion, a Worm on the drum gradually decreasing in pitch inthe direction of and to the largest part of the drum and then graduallyincreasing in pitch in the direction of and to the front end of thedrum, and drum operating means.

In testimony whereof I aiiiX my signature in presence of two Witnesses.
